Methods To Construct Kids Furniture
Follow the method shown in the photos, to make such limited inside rabbets or grooves on a circular saw. First raise the saw blade to a height equal to the depth of the rabbet desired. (If a groove is being cut, a dado saw blade is used.) The next step after the fence set at the proper distance from the blade, use a square to mark vertical lines on the fence, one line indicating where the outside arc of the saw blade first emerges above the table and starts to cut, and the other line pointing to where the inside arc of the blade descends below the table and the cutting ceases.
These lines are the only ones needed on the table saw, for cutting a groove. But for cutting a rabbet a similar set of lines should be drawn horizontally across the table surface to indicate these same limits of the saw cut. The next step is, you have to mark two lines across the top of the wood directly over the points where the groove or rabbet underneath is to begin and end. Then, without turning on the saw, lay the wood over the blade and flush against the fence, back it up until the forward line on the wood is lined up with the outside line on the fence, and put a clamp on the fence at a point where it will hold the wood in this position and not let it slip back.
Now, you have to turn the saw on, back the wood against the clamp stop, hold at an angle above the spinning saw blade, and then carefully lower it down on the blade until it is lying flat on the table top. Immediately advance the wood along the fence until the rear line on the wood comes into line with the rear line on the fence. Then stop and remove the wood. If you are cutting a rabbet, turn the wood on end and repeat the operation, this time using the guide lines on the table surface to start and stop the cut.
